INSTALLATION

Window wiper kits in the WW57 Series are designed to operate with an AC voltage to turn
on the wiper. However, the kits must be modified to use +5 to +10 VDC to turn on the wiper
when the kits are used with Pelco’s receivers.

If you are going to use a Pelco receiver, proceed to the
tion.

If you are going to use equipment that provides AC power to control the wiper, proceed to
the

Window Wiper Kit Installation

section.

WINDOW WIPER KIT MODIFICATION

Modify your wiper kit if it is to be operated from any of the following Pelco receivers:

CX9000 Series
WX8000 Series
LRD41 Series
ERD97P21-U with the ERD97P-AUX option board

This modification only changes the voltage that is required to turn on the wiper. The wiper
motor still requires AC voltage (refer to Figure 1).

To modify a kit:

1. Remove the circuit board cover from the wiper motor/control assembly and remove the
circuit board (PCB9000275 Rev. E). Refer to Figure 10 for parts locations.

Refer to Figure 2 for steps 2-5.

WINDOW WIPER KIT INSTALLATION

For the following instructions, refer to Figure 10, if necessary. Table B lists the parts shown
in Figure 10.

1. Turn off power to the enclosure.

2. Unlatch and raise the enclosure lid. The gas spring will hold the lid in place when it is
fully opened.

3. Remove the camera and sled.

4. EH5723/EH5723L and EH5729/EH5729L Models Only - Remove the vent
grill inside the enclosure at the rear of the unit.

5. EH5723-1, -2, -3/EH5723L-1, -2, -3 Models, and EH5729-1, -2, -3/

EH5729L-1, -2, -3 Models Only

a. Unplug the electrical connector on the fan.
b. Remove the three screws that secure the fan plate and fan to the enclosure.
c. Remove the fan plate and fan.
d. Remove the fan from the fan plate.
e. Attach the fan to the fan plate of the window wiper assembly in the same orienta-

tion that it was attached to the original fan plate.

6. Refer to Figure 5 and insert the wiper shaft into the green bushing on the fan plate of
the wiper motor/control assembly.

7. Insert the motor/control assembly into the enclosure and attach the assembly to the
enclosure with the hardware that is supplied:

a. Slip the blue, white, and black wiper wires into the slot at the bottom of the fan

plate so that the white plug is on the opposite side of the fan plate from the wiper
circuit board housing.

b. On all models except the EH5723 and EH5729, remove the screws on the sides

of the circuit board in the enclosure so that the circuit board can be moved out of
the way to install the wiper motor/control assembly.

c. Place the assembly into the enclosure with the wiper circuit board housing facing

toward the rear of the enclosure and the fan plate against the camera sled track.

d. Hook the rear of the circuit board mounting over the screw installed at the top of

the enclosure’s rear panel. Secure the circuit board mounting to the enclosure
with the acorn nut.

e. Attach the bottom right and bottom left sides of the fan plate to the camera sled

track with screws and lock washers.

f. On all models except the EH5723 and EH5729, reinstall the circuit board.

8. Reconnect the electrical connector to the fan.

9. Remove the latch on the side of the enclosure where the wiper shaft is located.

10. Slide the support bracket onto the wiper shaft. Using the longer screws supplied in the
wiper kit, attach the latch and support bracket to the enclosure.

11. Slide the flange bearing over the bearing pin as shown in Figure 5, and slide the cam
track over the flange bearing. Only the tautness of the drive shaft holds the flange
bearing in place.

12. Refer to Figure 6 and slip the flex coupler over the drive shaft.

13. Remove the hole plug from the wiper shaft hole in the front of the enclosure.

14. From the outside of the enclosure, install the green bushing into the wiper shaft hole.

15. Remove the two screws on the bottom of the enclosure under the window and install
the wiper assembly with two Allen cap screws that are supplied in the parts bag. Make
sure the shaft of the wiper arm goes through the green bushing on the front of the en­closure.

16. Looking at the front of the enclosure from the outside, position the wiper blade so that
it is on the left side of the window as you look at it.

17. Slide the flex coupler over the wiper arm shaft and tighten the two screws in the cou­pler to secure it to the drive shaft and the wiper arm shaft.

18. Remove the cover over the circuit board on the wiper motor/control assembly.

19. Refer to Figure 7 and set either of the following two options:

a. The time between wiper strokes can be adjusted between 3 and 10 seconds by

rotating the potentiometer R8. Turn the adjustment clockwise to increase the time.
The potentiometer only makes one revolution.

or

b. The wiper can be set to operate continuously by placing the delay jumper at JP6

in the OFF position.

20. Verify that jumpers JP1 through JP5 are set for the correct input voltage.

If you modified the circuit board, place JPI in the 1–2 position. This will route the DC
voltage from the receiver to the on/off circuit of the wiper. Never place the jumper in
the 2–3 position or the wiper will not work.

21. Replace the cover over the circuit board on the wiper motor/control assembly.

WARNING:

If you
use an AC control,
AC high to turn on

the wiper must come from
the same circuit that provides
power to the wiper. This is
because the wiper and the
on/off control share the
same AC neutral. Refer to
Figure 9. This will prevent
damage to the wiper.

22. If you modified the circuit board, connect the green wire from the anode of D3 to either
of the following:

• If your enclosure has the O/I-PCB circuit board (PCB9000276), connect the wire

to the LENS COM connector (refer to Figure 8).

• If your enclosure does not have the circuit board, connect the wire to the LENS

COM connector on your pan/tilt unit or receiver.

23. EH5723 and EH5729 Models Only – Wire the wiper assembly to power as fol-
lows:

Black wire AC HI
White wire AC NT
Blue wire Wiper on/off control

If you modified the circuit board, wire the wiper on/off control to an auxiliary output on
the receiver.

All window wiper assemblies use 15 watts of power. If you are using 24 VAC, refer to
Table A to determine the size of wire to use.

24. All Models Except the EH5723 and EH5729 – Wire the wiper assembly to
power as follows:

a. Remove the plastic cover from the power supply section of the circuit board in

front of the fan plate.

b. Connect the plug from the wiper assembly into the W/W socket on the circuit

board.

c. Wire the wiper on/off control.

If you modified the circuit board, wire the wiper on/off control to an auxiliary out­put on the receiver.

Pelco Manual C1432M-C (11/99) 9

If you are installing the wiper kit in a Legacy enclosure, power for the wiper is
supplied through the 37-pin connector on the pan/tilt unit as follows:

AC High Pin 15
AC Neutral Pin 16
Wiper On/Off Control Pin 25

If you are installing the wiper kit in a non-Legacy unit, power for the wiper is sup­plied as follows:

AC High Pin 1 of TB2 on the O/I-PCB circuit board (refer to Figure 8)
AC Neutral Pin 2 of TB2 on the O/I-PCB circuit board
Wiper On/Off Control Pin 1 of TB3 on the O/I-PCB circuit board

Pins 15 and 16 on Legacy enclosures and pins 1 and 2 of TB2 on non-Legacy
enclosures also provide power for other enclosure accessories, such as the fan
and heaters. Make sure that this wiring can handle the additional power for the
wiper. All window wiper assemblies use 15 watts of power.

d. Replace the plastic cover over the power supply on the circuit board.

25. Reinstall the camera and sled.

26. Close the enclosure lid.

27. Turn on power to the enclosure.

Table A. 24 VAC Wiring Distances

The following are the recommended maximum distances for 24 VAC applications and are
calculated with a 10-percent voltage drop. (Ten percent is generally the maximum allowable
voltage drop for AC-powered devices.)

Wire Gauge

EXAMPLE:

An enclosure
that requires 80 vA and is
installed 35 feet (10 m) from
the transformer would
require a minimum wire
gauge of 20 AWG.

NOTE:

Distances are
calculated in feet; values in
parentheses are meters.
